We are working on a design/build for a private commercial building with an attached 30,000 sf repair hangar. The owner has a requirement for power in a floor trench. The catch is that he needs both 30A and 100A 208v receptacles in a 4-pole, 5 wire setup. The only receptacles I can find that are available in that setup are the Crouse Hinds BHR receptacles. The issue with these is that they must be mounted veritically with the contacts pointed down. This is not a very friendly installation method for the end user. Does anyone have any suggestions of other Class 1 Div. 1 devices?
